Class IDX

java.lang.Object

org.ojalgo.netio.IDX

public abstract class IDX
extends Object

Reads IDX-files as described at THE MNIST DATABASE page. The elements/pixels/bytes are written to the ArrayAnyD instance in order as they're read from the file. The indexing order then needs to be reversed, and that causes the images to be transposed.
